Distributed control of a car suspension system

Active suspension control system are used in today cars because of their ability to manage the compromise between ride comfort and vehicle road-handling. They constitute a typical example of distributed control systems. In this paper, the ride controller part of an active suspension sys-tem is presented and evaluated, taking into account its distributed architecture. The simulations are realized with the Matlab/Simulink toolbox TrueTime, which allows the simulation of the controlled system, integrating simple models of its implementation (task execution, processor scheduling, network transmission...). We show, through a simulation example, how implemen-tation related parameters can have a considerable impact on the robustness of the controlled system
